Chile Peppers, Pasilla
Pasilla Negro Chile Peppers
Pasilla chiles have a long, purple pod similar to ancho chile peppers.
Pasillas are one of the most popular chiles. Pasilla teams with ancho and mulato chiles (a version of ancho) to form the "holy trinity" used in making moles. They're great for sauces of all sorts. They clock in at 3-5 heat level, on a scale of 10.
